LG | 42LG6000 | Loose scratches in the image | The problem is in the two 100uf smd capacitors on the board between the t-con and the mainboard (c403 and c398). the capacitors are both in the lower right corner of the board. just replace these capacitors and the problem will be solved. | Shakti | |
LG | 14FK3RB | Does not come out of standby, 91k resistors ok, I measured the 5 volts on the ic803, I measured the ic806, it did not release the 9 volts, due to the micro not releasing tension on pin 29, I soldered a 10k resistor on pin 4 to pin 1 of the ic 806 TV turned on but with the image distorting, I concluded that it was one of the crystals | O cristal x502(32.768 | I replaced the x502 crystal (32.768) and removed the resistor that I placed on the ic806 and the TV was ok | DTEC-ELETRONICA-Massapê-ce |
